@OutofPrintArchive Most bugs in FF aren't disruptive. FF4's item duplication was widely published.
I think that reviewer would have considered the 2011 PSP version the best way to play. I didn't have that handheld, but I heard plenty of praise for it before the Pixel Remasters.
I really enjoyed the voice acting and script in the 3D version. It also had a music player in the extras. You could close the lid of the DS and instead of going into sleep mode it would still play the soundtrack.
